    powerpc: Convert VDSO update function to use new update_vsyscall interface
    
    This converts the powerpc VDSO time update function to use the new
    interface introduced in commit 576094b7f0aa ("time: Introduce new
    GENERIC_TIME_VSYSCALL", 2012-09-11).  Where the old interface gave
    us the time as of the last update in seconds and whole nanoseconds,
    with the new interface we get the nanoseconds part effectively in
    a binary fixed-point format with tk->tkr_mono.shift bits to the
    right of the binary point.
    
    With the old interface, the fractional nanoseconds got truncated,
    meaning that the value returned by the VDSO clock_gettime function
    would have about 1ns of jitter in it compared to the value computed
    by the generic timekeeping code in the kernel.
    
    The powerpc VDSO time functions (clock_gettime and gettimeofday)
    already work in units of 2^-32 seconds, or 0.23283 ns, because that
    makes it simple to split the result into seconds and fractional
    seconds, and represent the fractional seconds in either microseconds
    or nanoseconds.  This is good enough accuracy for now, so this patch
    avoids changing how the VDSO works or the interface in the VDSO data
    page.
    
    This patch converts the powerpc update_vsyscall_old to be called
    update_vsyscall and use the new interface.  We convert the fractional
    second to units of 2^-32 seconds without truncating to whole nanoseconds.
    (There is still a conversion to whole nanoseconds for any legacy users
    of the vdso_data/systemcfg stamp_xtime field.)
    
    In addition, this improves the accuracy of the computation of tb_to_xs
    for those systems with high-frequency timebase clocks (>= 268.5 MHz)
    by doing the right shift in two parts, one before the multiplication and
    one after, rather than doing the right shift before the multiplication.
    (We can't do all of the right shift after the multiplication unless we
    use 128-bit arithmetic.)
